New Jam
Same song.
Same second.
No server.
Start a Jam, share a link, and your friends' players follow yours, from any network. Peers connect directly over iroh. Only the state travels between you; every player streams its own audio from SoundCloud.
- 1Host a Jam. Your player becomes the authority: track, position, play and pause.
- 2Share the link. Friends paste it anywhere in cloudrs to join.
- 3Stay in sync. Clock offset and drift correction keep everyone on the beat.

Architecture
A clean signal chain.
A Rust workspace patched like a modular rack: every crate is one module with one job, cables only run one way, and the tests fail if anyone patches around them.
